A system of microring resonators (MRRs) connected to an optical modified add/drop filter system is used. The optical soliton pulse of 60 GHz frequency band can be generated and used for millimeter waves in radio over fiber (ROF) applications. Wireless Personal Area Network (WPAN) as IEEE 802.15.3c is one of the applications for the ROF. The system uses chaotic signals generated by a Gaussian laser pulse propagating within a nonlinear MRRs system. The chaotic signals can be generated via a series of MRRs. The IEEE 802.15.3c standard operates at the 60 GHz frequency band, and it is applicable...

The new integrated system of visible free space optic and broadband powerline communication which uses already installed powerline cables and white LEDs as a communication channel is presented. The currently exist problems in integrated system degrades the whole system performance significantly. Therefore, in this work, an optimum OFDM modulating signal power, proper DC biasing point and LED dynamic range are presented for the integrated system. Besides using OFDM modulation a practical LED model is also presented and the performance of integrated system in terms of OFDM signal power versus...
